In Great-Britain November 2, 1948 This invention relates to. wrappers or containers made of cardboard, strawboard, pasteboard or other foldable-sheet material comprising sheets which. are spaced apart, being either separate sheets or a folded sheet, which are to be secured together and closed at their ends. The object of the invention is to provide an improved construction of wrapper or container which is easy to use, not liable to accidental opening. and adds considerably to thestrength of the package.

The invention is illustrated inthe accompanying drawings, in which I Figure 1 is a perspective view showing one form of container to which the inventionmay be applied.

Figure 10 is a section on the line Z-Z of Figure 9, and

Figure 11 shows one of the blanks used for making a tie'for use withthe containers shown in Figures 6 or 9.

Figure 1 shows a container already known. The container is suitable for use as a book-Wrap. This'container is made from a blank illustrated in Figure 3 and has two opposite side-walls 20, 2|, which are permanently connected together at theiredges 22, 23, and by an intermediate edge wall 24. One end of the container may be permanently closed, but in the form illustrated both ends are closed by means of hinged flaps. The wall has a flap hinged to it along the creaseline so that the portion 26 of the flap can with a second crease-line 21 parallel to the crease-line 25 so that the portion 28 of the flap can be folded at right-angles to the part 29.

The'dimensions of the flap are such that when it is folded into the container as shown in Figure2, the portion 28 of thefiap extends across On the free 6 Claims. (01. 22947) edge of the flap there are formed any desired number of lugs 29.

The wall 2| is formed with a similar flap having two parts 30, 3| which can be folded inside the container to an L-shape, as shown in Figure 2, the part 3| lying inside the container with respect to the part228 of the other flap.

The flap 30 is formed with apertures 32 corresponding in number, size and spacing to the lugs 29 on the flap 26, 28 so that, when folded into the container, the lugs 29 engage in these apertures 32 and lock the parts in this position.

The parts 26 and 30 of the flaps reinforce and stiffen the marginal edges of the walls 20, 2| when in their closed position, and the parts 28,

' 3| of the'flaps which extend across the width of fold inside the container; the. flap is also formed the container reinforce it against collapsing and side wall 46 is formed with a flap 48, 49 similar to the flap 30,,3l of Figurez and provided with an aperture-50 adjacent the crease between the two parts of the flap. The wall 41 is provided with a flap 5|, 52,- 'which is similar to the flap 26, 29 of Figure 2,but the lug which engages the aperture 50 in the other flap is extended at 53 to form a long tongue which is passed through the aperture 50 and through an aperture 54 in the wall 46 and is then folded around the ends of the walls 46, 41 as shown at 55, 55 and the end of the tongue 51 is inserted through an additional aperture 58 in the wall 41 to enter between the parts 49, 52 of the two flaps where it is securely retained. The part 55 of this tongue constitutes a tie which prevents separating movement of the two walls 45, 41 but when it is desired to open the end of the container, the tongue 51 is withdrawn, thereby releasing the tie, after which the two fiapscan be withdrawn, as in the construction illustrated in Figure .2.

I Figure 5 shows an alternative construction which has a general resemblance to Figure 4, but the tongue which constitutes the tie is formed on the flap which has the apertures instead of the flap which has the lugs. The side wall 59 is formed with the flap 60, 6| which has lugs on it exactly like the flap 26, 28 of Figure 2 and the side wall.62 is formed with a flap 63. 64 which is formed with the apertures to receive the lugs,

but this flap is extended as a tongue beyond 64 at 65, 66, 61, 68 and this tongue is threaded through an aperture 69 in the Wall 59 and then folded round over the ends of the walls 59, B2 and inserted through the aperture in the wall 62 so as to lie beside the part 64 of the flap on the wall 62.

Instead of forming the tie, which is to secure the sidewalls together, as an extension of one of the flaps, it may be formed as a separate member which is engaged with each of the side walls and for this purpose a preferred construction as illustrated in Figures 6, 7, 8 and ,llmay be used. A blank of cardboard or like sheet material is formed of T-shape as illustrated .in

Figure 11, comprising a cross-bar indicated generally by the reference H and a stem 12 which forms a tongue. The part H is creased so that it can be folded lengthwise into a box-like'section as shown in Figure .7, whereof the walls are shown at T3, l4, l5 and 16.

Preferably this blank is associated back-totback with .a similar blank and as shown in Figure '7, comprising the parts 11, H3, 19 and 8fl; -packingpieces 8| (see Figures 7 and ll) :areiinserted between the-two parts 15 and 19,:allthesepaits being secured together in ,any convenient manner. The packing pieces iii are :spaced apart as shown in Figurellso as to leave a space between themat least equal in width to the width of the'stem .or tongue 12. 7

Each of the two sheets or walls 82, 83 which are to be tied together isprovided with-anaperture near the marginaledge at a point which,

when'the bex-like sections 73, 1'4, 1'5, '15 and 11, f 1-8, 19, blliare insertedas shown inFigures land 8, will enable the tongues .12 and '84 to lee-passed outwards, each through its appropriate taperture,.and folded "around the edges of thesh'eets 82, 183 and have their ends inserted -as shown at 85, 83 between the :parts 15, 19in the space between the distance pieces 8| where'they are 'frictionally retained; the two sheets -8Z, :88 are thereby edectively retained ."against :accidental separation, but they can be separated -b-y--withdrawing the tongues '85, 86 so that they can be drawn out through the vapertureiin thessheets.

It will be seen that the "composite-tie member constituted by "two blanks 'H, 'innaddition to securing the two sheets 82, 83 together alsoacts as a closure for the space between them, and provides reinforcement for the e'dges of the sheets .and prevents them from being collapsed together.

It will further be seen that a :single blank 11 folded in the manner above described could be ranging that the tongue on it after passing outwards through one sheet is 'folded around the :edges of both sheets'and is inserted .throughthe aperture in the second sheet.

The tie member :as illustrated in -Figures'? and '8 may be associated with the known construc- "tion illustrateclin Figure '1, such :an arrangement being shown in Figures 9 and 10. Thecontainer shown in figure 9 has :all the parts shown in Figures .1, 2 and 3 withthe same references-rattached thereto, .but additional apertures are 'provided at 88 in the walls 20 and 2| and also apertur'rs 59 in the Jflaps connected respectively to these walls, in order *to accommodate the tongues. The two flaps arefoldedin' in the manner describeduvith referencetto "Figure :l, and the composite tie member then inserted between the parts 26-and '30 of'th'eflaps withthetongues extending outwards through the apertures 89 "used as ,a tie member and reinforcement, byar- 7 4 and '88, and then bent around the ends of the walls so that the free ends of the tongues are tucked in between the box-like portion of the tie to be retained therein.

I claim:
